Since rocblas.dll and hipblaslt.dll are copied to torch/lib, rocblas and hipblaslt directories are needed to be stored there too (otherwise we have an error after wheel installation while searching for files in rocblas/library and hipblaslt/library which doesn't exist). This PR fixes this issue.

Follow up to @ezyang's PR #153020 , but better uses PEP621 to reduce redundant fields and pass through metadata better to uv, setuptools, poetry and other tooling.
* Enables modern tooling like uv sync and better support for tools like poetry.
* Also allows us to set project wide settings that are respected by linters and IDE (in this example we are able centralize the minimum supported python version).
* Currently most of the values are dynamically fetched from setuptools, eventually we can migrate all the statically defined values to pyproject.toml and they will be autopopulated in the setuptool arguments.
* This controls what additional metadata shows up on PyPi . Special URL Names are listed here for rendering on pypi: https://packaging.python.org/en/latest/specifications/well-known-project-urls/#well-known-labels
These also clearly shows us what fields will need to be migrated to pyproject.toml over time from setup.py per #152276. Static fields be fairly easy to migrate, the dynamically built ones like requirements are a bit more challenging.
Without this, `uv sync` complains:
```
error: No `project` table found in: `pytorch/pyproject.toml`
```

This PR adds two main parts:
- shim.h stable C APIs into torch::Library APIs
- a higher level API in torch/csrc/stable/library.h that calls into this shim.h + otherwise is self contained
Goal: custom kernel writers should be able to call the apis in the directories above in order to register their library in a way that allows their custom extension to run with a different libtorch version than it was built with.
Subplots resolved:
- Do we want a whole separate StableLibrary or do we want to freeze torch::Library and add `m.stable_impl(cstring, void (*fn)(void **, int64_t, int64_t)` into it
- Yes, we want a separate StableLibrary. We cannot freeze Library and it is NOT header only.
- Should I use unint64_t as the common denominator instead of void* to support 32bit architectures better?
- Yes, and done
- Should I add a stable `def` and `fragment` when those can be done in python?
- I think we do want these --- and now they're done
- Where should library_stable_impl.cpp live? -- no longer relevant
- I need some solid test cases to make sure everything's going ok. I've intentionally thrown in a bunch of random dtypes into the signature, but I still haven't tested returning multiple things, returning nothing, complex dtypes, etc.
- Have since tested all the torch library endpoints. the others can be tested in a followup to separate components that need to be in shim.h vs can be added later

# Fix typo errors across PyTorch codebase
This PR fixes various spelling errors throughout the PyTorch codebase to improve documentation quality and code readability.
## Changes Made
### Documentation Fixes
- Changed "seperate" to "separate" in multiple files:
- `setup.py`: Build system documentation
- `torch/_library/triton.py`: AOT compilation comments
- `torch/csrc/dynamo/compiled_autograd.h`: Node compilation documentation
- `torch/export/_unlift.py`: Pass population comments
- `torch/export/exported_program.py`: Decomposition table notes
### Code Comments and Error Messages
- Changed "occured" to "occurred" in:
- `test/mobile/test_lite_script_module.py`: Exception handling comments
- `torch/export/_draft_export.py`: Error message text
- `aten/src/ATen/native/cuda/linalg/BatchLinearAlgebra.cpp`: MAGMA bug comment
- `torch/csrc/utils/python_numbers.h`: Overflow handling comment
- `torch/csrc/jit/OVERVIEW.md`: Graph compilation documentation
- `torch/_dynamo/symbolic_convert.py`: Error explanation
### API Documentation
- Changed "fullfill" to "fulfill" in `torch/distributed/checkpoint/state_dict_loader.py`
- Changed "accross" to "across" in:
- `torch/csrc/distributed/c10d/ProcessGroupNCCL.cpp`
- `torch/distributed/distributed_c10d.py`
## Motivation
These changes improve code readability and maintain consistent spelling throughout the codebase. No functional changes were made; this is purely a documentation and comment improvement PR.
## Test Plan
No testing required as these changes only affect comments and documentation.

Ok, the build flag seems to have been broken for a while since the function it calls doesn't exist anymore.
Repurposed it to enable dispatcher printing (which requires a full (and slow) debug build otherwise).

Useful for code reuse for Metal shader build both for eager mode and MPSInductor, but it requires one to implement `_cpp_embed_headers` tool that, as name suggests, would preprocess and embeds the for shader to be used in dynamic compilation.
Test using:
- `TestMetalLibrary.test_metal_include`
- Moving `i0`/`i1` implementation to `c10/util/metal_special_math.h` and call it from `SpecialOps.metal` shader, which now looks much more compact:
```metal
template <typename T, typename Tout = T>
void kernel
i0(constant T* input,
device Tout* output,
uint index [[thread_position_in_grid]]) {
output[index] = c10::i0(static_cast<Tout>(input[index]));
}
```

Description:
1. Quantize Linear Layer Weights to 4-bits:
Quantize the weights of the Linear layer to 4 bits, using symmetric quantization.
Pack two 4-bit weights into one uint8 container.
Choose a quantization scheme (channel-wise or group-wise), with the group size being a multiple of 32.
2. Prepare Quantized Weights, Scales, and Optional Bias:
After quantizing, obtain the quantized_weights, scales, and groupsize.
If the original Linear layer has a bias, prepare it as well.
3. Pack the Weights Efficiently:
Use torch.ops.aten._dyn_quant_pack_4bit_weight to optimally pack the weights, scales, and optional bias.
```python
packed_weights = torch.ops.aten._dyn_quant_pack_4bit_weight(weight, scales_and_zeros, bias, groupsize, in_features, out_features)
```
Input parameters should include:
in_features and out_features (the same as the Linear layer’s corresponding parameters).
4. Perform Dynamic Quantized Matrix Multiplication:
Use torch.ops.aten._dyn_quant_matmul_4bit to perform matrix multiplication with quantized weights.
```python
output = torch.ops.aten._dyn_quant_matmul_4bit(input, packed_weights, groupsize, in_features, out_features)
```
Inputs required include:
The input tensor, packed_weights , groupsize, and the in_features and out_features.

Notable new features for SDPA operators on AMD systems from AOTriton 0.8b:
1. Nestedtensor support;
2. MQA/GQA support;
3. Restore Efficient attention support for causal=True and seqlen_q != seqlen_k cases;
+ The kernel should use top-left alignment, bottom right alignment will be added later
4. Move gfx1100 (RX7900/W7800/W7900) out of experimental support status.
However, users are strongly recommended to update to ROCM 6.2.4, notably for
its firmware updates.
Related unit tests are enabled as well.
Notable related changes from AOTriton 0.8b:
1. AOTriton 0.8b moves the GPU kernel out of libaotriton.so to a separate directory `aotriton.images`;
2. LZMA replaces ZSTD as GPU kernel compression algorithm for better compression ratio: aotriton0.8b (.so + aotriton.images take 350MB) compared to aotriton0.7b .so: 800MB
3. The compression cannot be disabled now, and `liblzma` is hard run-time dependency.
+ Should not be a problem, since `lzma` is part of Python Standard Library

Summary:
In this diff we implement a way to ensure the internal thrift schema from cfgr (configerator/structs/caffe2/torch/export/schema.thrift) and the schema in OSS (torch/_export/serde/schema.thrift) are in sync, by adding a unittest to reflect on the type names and fields from each schema and compare them field by field.
When we detect new fields/types from torch/_export/serde/schema.thrift, there'll be a test failure on the trunk and the error message hints people to add the missing field/type to the thrift schema from cfgr, so that they are always in sync in practice.
Test Plan: buck test mode/opt caffe2/test:test_export -- -r test_thrift_schema_in_sync
